2 Claims. l

This invention relates to burners of the type and kind generallyemployed in restaurants, lunchrooms and similar places. Moreparticularly, the invention deals with a burner unit which is mounted toswing from a normal operative position, to a raised or perpendicularposition to facilitate cleaning and repair to the burner, :as well asthe counter or table surface disposed beneath the burner. Still moreparticularly, the invention deals with a burner unit of the characterdescribed having means adapting the same for use with stove accessories,such for example, as broilers.

The novel features of the invention will be best understood from thefollowing descriptions when taken together with the accompanying drawingin which certain embodiments of the invention are disclosed, and inwhich the separate parts are designated by suitable reference charactersin each of the views, and in which:

Fig. l is a plan and sectional View of a burner unit made according tomy invention, with part of the construction broken away.

Fig. 2 is a section on the line 2-2 of Fig. 1, on an enlarged scale,with part of the construction broken away and indicating in dottedlines, the raised position of the unit.

Fig. 3 is a partial section on the line 3-3 of Fig. l, on an enlargedscale, and indicating part of a broiler.

Fig. 4 is a partial section on the line 4--4 of Fig. 2; and

Fig. 5 is a partial section on the line 5--5 of Fig. 4.

In the drawing, I0 represents what I term a swingable burner unit which,as indicated in Fig. 2, is adapted for mounting on a counter or othersupport I I to normally assume a horizontal position thereon, as shownin full lines and to be raised to a vertical position at the back of thecounter, as indicated in part, in dotted lines in said ligure. In theconstruction shown, the unit I0 is economically constructed from aU-shaped strip or band, fashioned to form a iront Wall portion I2 andside walls I3 and I4, this U-shaped structure forming the frame of theunit, which is pivoted to a fixed angle-iron strip I5, secured to therear portion of the counter II, the pivot being formed by pins IB and I1:arranged in upstanding end bearing walls I8 and I3 on the strip I5.

Considering Fig. 3 of the drawing, it will appear that these bearingwalls extend well above the vertical back portion 20 of the angle-ironstrip. Arranged upon the frame is a top grill 2 plate 2|, which forms acover for the top of the frame or the burner unit and this grill platecan be detachably mounted in any desired manner. The plate has anaperture 22 therein, note Fig. 3, to facilitate coupling of a broiler,as later described.

Joining the walls I3 and I4, inwardly of the pivots IB and I'I, is across-strap or bar 23, which forms a support for one of a number of gasburners 24, only one of which is shown in the accompanying drawing, asWell as .a support for a gas service or supply pipe 25 for servicing thebroiler, as later described. The burners 24 may be of any desiredconstruction, as will be apparent.

Mounted in the frame of the unit I0, on the inner surface of the frontwall I2 of the frame, is a long gas supply tube 26, preferably having afree mounting in the side walls I3 and I4, asindicated by the clearancein the aperture 2, in- Wardly of the supporting pin 25. This mountingfacilitates alinement of the tube 25 with the swinging mounting of thegas supply pipe 23, which couples with the tube 26. The pipe 23 has atits inner end, a coupling 33, having a conical ground seat in opposedwalls thereof, as seen at 3 I for a conical extension 32 on a fitting33. The conical extension 32 is apertured, as seen at 34, for supply ofgas to the pipe 29, and thus to the supply tube 2B. On the extension 32is an outwardly projecting threaded rod or reduced threaded portion 35for reception of a nut 36 to control tensioning of a spring 3l, whichmeans the tapered extension 32 is in seated position in the bores 3|, aswill be apparent. The taper is exaggerated in the accompanying drawingsimply from a standpoint oi clarification, and it will also be apparentthat the extent of the bearing surfaces 3i can be varied.

The fitting 33 comprises a relatively high tubular body 33, from whichthe extension 32 extends at the upper portion thereof, as clearly seenin Fig. 5, the gas supply pipe or a litting thereon, as at 39, beingcoupled with the tubular body 3B, as clearly seen in Fig. 4 of thedrawing. The fitting 39 .passes through the back wall 2t and is threadedinto the tubular body 33 and a nut 40 is employed to secure the parts infirm engagement with a xed angle-iron strip I5. To avoid strains on thefitting 33, as a Whole, the tubular body has an extension 4I, with a pin42 arranged in the Wall 20, to act las a key.

Considering Figs. 2 and 4 of the drawing, it will be apparent that theaxis of the extension 32 is in direct alinement with the pivots I6 andIl,

so that in swinging the unit vertically, the pipe 29 swings on theextension 32, thus maintaining constant supply of fuel at all times tothe tube 26 and the burners. It will be understood that this willmaintain the conventional pilot lights which are employedl invburnersfof the kind under consideration in operation. Pilot lights arenot shown, as they form no part of the present conception. Y A Y Y InFig. l of the drawing, theV unit -lil-is.-hro'lten away and only oneburner 2-4 is shown. However, a number of these burners may'rbe4employed, andY each burner will have a control valve., as at. 43 noteFig. 2, directly coupled with thetubeZ. and having a ingerpiece portion44 disposed outwardly of the front wall l2. .At the rear end of thevalve is the usual Venturi' tube` il?, "leading'to the burner 24, tocontrol admission of airrsnpply to the burner.

The rear end. of lthe pipe .25. has a. fitting 45 having an upwardlydirectedgas dischargednorzzle -41 which extends. above the frame andthrough the aperture 22 in the platefzl. The aperture22 facilitatesreception of the downwardly extending Venturi tube 48 of a broiler, partof whichis .indicated in dot and dash lines at.49 in Fig. 3. The broilercan be ofthe general type and kind disclosed in my prior. applicationSer. No. 58,569l filed November 5, 1948, in which a similar type of tubeis employed. rThe tube 4 8. includes an adjustable apertured sleeve "5Dwhich acts as an air valve controlling the supply of air tothe Venturitube 48.

From the foregoing, it will be apparent. that such accessories as abroiler can be arranged upon the plate/2l and be serviced from thesupply pipe 25, which has a valve control forwardly of the front wallI2, as-seen at 423.'. In other Words, similar to the ngerpiece control44 of the valve 43.

With a burner unit of the character described, it will be apparent thatthe entire unit can be swung from the full line horizontal position,seen in Fig. 2, toa raised position at the back oa counter or table Hfacilitating cleaning of the various parts of thelunit, as well as. theupper surface o'f the counter or table. When the unit is in the raisedposition, the counter or table can be utilized for other purposes., Inraising the unitthe plate 2l can be removed so as to clean the upperstructure of the unit prior to moving the same into thev raised positionand all of Vthe foreign matter or removed particles will collect on thecounter and can then be removed therefrom, or--a collecting sheet canbefirstdisposed on the counter before the cleaning operations-areperformed.

It will be understood that my invention is adapted for use in connectionwith units of any type or kind and using any type or hind of burners. Inthis connection, the grill plate can be of such structure as to fullyexpose some of the burners for direct heating of receptacles arrangedthereover.

Byconstructing the unit of the. metal strips and other parts, it will bereadily seen that the unit can be constructed very economically. Theonly parts which are of special construction are the fittings 3U, 33 and46. All other fittings, pipes and the like can be of standardconstruction.

Throughout the speciiicati'on, reference is made to a counter or tabletop, and it is understood'that this counter or table top may compriseany relatively fiat horizontal supporting surface upon which the burnerunit is arranged. In some instances it may comprise the top of a range.The distinctive feature in thepresent invention resijdesin the provisionof the: swinging frame supp'orting'burner or similar service mediums, sothat at. any time, the unit can be swung into a raised position forcleaning or other purposes, as hereinlset forth.v
